The drains of these three vertical DMOS chips are mounted on separated leadframes. The sources are connected to individual pins, so the BTS 7710 GP can be used in H-bridge- as well as in any other configuration. The double high-side is manufactured in SMART SIPMOS(R) technology which combines low RDS ON vertical DMOS power stages with CMOS control circuitry. The high-side switch is fully protected and contains the control and diagnosis circuitry. To achieve low RDS ON and fast switching performance, the low-side switches are manufactured in S-FET logic level technology. The equivalent standard product is the BUZ 103 SL. In contrast to the BTS 7710 G, which consists of the same chips in an P-DSO-28 package, the P-TO263-15-1 PowerPack offers a much lower thermal resistance, which opens up applications with even higher currents in the automotive and industrial area.

Buffer amplifiers are driven by these stages and convert the logic signal into the necessary form for driving the power output stages. The inputs are protected by ESD clamp-diodes. The inputs IL1 and IL2 are connected to the gates of the standard N-channel vertical power-MOS-FETs. Output Stages The output stages consist of an low RDS ON Power-MOS H-bridge. In H-bridge configuration, the D-MOS body diodes can be used for freewheeling when commutating inductive loads. If the high-side switches are used as single switches, positive and negative voltage spikes which occur when driving inductive loads are limited by integrated power clamp diodes. Short Circuit Protection The outputs are protected against - output short circuit to ground - overload (load short circuit). An internal OP-Amp controls the Drain-Source-Voltage by comparing the DS-VoltageDrop with an internal reference voltage. Above this trippoint the OP-Amp reduces the output current depending on the junction temperature and the drop voltage. In the case of overloaded high-side switches the status output is set to low. Overtemperature Protection The high-side switches incorporate an overtemperature protection circuit with hysteresis which switches off the output transistors and sets the status output to low. Undervoltage-Lockout (UVLO) When VS reaches the switch-on voltage VUVON the IC becomes active with a hysteresis. The High-Side output transistors are switched off if the supply voltage VS drops below the switch off value VUVOFF. Data Sheet 5 http://store.iiic.cc/ 2001-02-01 BTS 7710 GP Status Flag The status flag output is an open drain output with Zener-diode which requires a pull-up resistor, c.f. the application circuit on page 14. Various errors as listed in the table "Diagnosis" are detected by switching the open drain output ST to low. A open load detection is not available. Freewheeling condition does not cause an error. 2 Truthtable and Diagnosis (valid only for the High-Side-Switches) Flag IH1 IH2 SH1 Inputs Normal operation; identical with functional truth table Overtemperature high-side switch1 Overtemperature high-side switch2 Overtemperature both high-side switches Undervoltage SH2 ST Remarks Outputs 0 0 1 1 0 1 0 1 L L H H L H L H 1 1 1 1 0 1 X X L L X X 1 0 detected X X 0 1 X X L L 1 0 detected 0 X 1 0 1 X L L L L L L 1 0 0 detected detected X X L L 1 not detected Inputs: Outputs: Status: 0 = Logic LOW Z = Output in tristate condition 1 = No error 1 = Logic HIGH L = Output in sink condition 0 = Error X = don't care H = Output in source condition stand-by mode switch2 active switch1 active both switches active X = Voltage level undefined Data Sheet 6 http://store.iiic.cc/ 2001-02-01 BTS 7710 GP 3 Electrical Characteristics 3.1 Absolute Maximum Ratings - 40 C < Tj < 150 C Parameter Symbol Limit Values min.
